Along with a nice look at how the franchise's visuals will be enhanced, the trailer confirms new maps alongside CS classics, more game modes, more weapons, ranked match-making, and cross-platform play are all on the way. See for yourself in the debut Counter-Strike: Global Offensive trailer:

"Counter-Strike took the gaming industry by surprise when the unlikely MOD became the most played online PC action game in the world almost immediately after its release in August 1999," Valve's Doug Lombardi said in a statement. "For the past 12 years, it has continued to be one of the most-played games in the world, headlining competitive gaming tournaments and selling over 25 million units worldwide across the franchise. CS: GO promises to expand on CS's award-winning gameplay and deliver it to gamers on the PC as well as the next gen consoles and the Mac."

Valve also announced that in celebration of the trailer's launch, the entire Counter-Strike franchise is now 75% off at Steam. The promotion is set to run throughout the weekend, offering six full games, including the original Counter-Strike, Counter-Strike: Condition Zero, and Counter-Strike: Source, for just $7.49.

Spy Guy says: It really is crazy to think the global phenom that is Counter-Strike started out as a mod for Half-Life. Cool to see the game's evolution in the trailer. And that Steam deal is nuts. So, what do you make of the debut CS: GO trailer?
